In [1]} the system to be controlled is linear and the up-link channel of the plant(s) is considered to be noise-free. Whereas, the downlink channel of the plants is assumed to be an AWGN feedback channel addressing the needs of low-mobility IIoT applications. The paper obtains a region of stability that indicates the necessary and sufficient values of communication parameters (i) information rate as well as (ii) length of error correction code blocks such that the stability of the system is insured. The paper assumes an ideal quantization and control policy to be followed across the network. Accordingly, the quantization as well as the control policy consider the history of all the communication and feedback signals exchanged between the plant and the controller. The paper also computes the average lower and upper bound of the task's cost function where the bounds are obtained as functions of communication parameters, information rate and length of error correction code blocks. The authors of [2]} solve a problem very similar to that of [3]}, where the difference is that in the former, the up-link channel of the plant(s) is considered to be noisy.
